IMPROVEMENTIN HEATING FEED-WATER APPARATUS 0F LOCOMOTIVES.

Specification forming part of Letters Patent No. 17,208, dated May 5, 1857.

To all whom it may concern.-

Be it known that I, PETER S. EBBERT, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Apparatus for Heating the .Feed-Water of Locomotive-Engines; and l do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l represents a side view of the apparatus. Fig. 2 represents an end view with the outer cylinder in section. Fig. 3 represents a transverse central section through the chimney and heating apparatus. Fig. 4 represents a horizontal section through the chimney or stack and the water-pipes.

Similar letters of reference, where they occur in the several figures, denote like parts 0f the apparatus in all.

The nature of my invention relates to the manner of introducing and escaping' the waste steam in between the double jackets that inclose the series of water-pipes, so as to economize its latent heat and prevent as far as possible the condensed steam from dripping over the heater or boiler aud corroding and staining it.

To enable others skilled in the art to make and use my invention, I will proceed to describe the same with reference to the drawings.

A represents a section of the front end of a locomotive-boiler, and B B the escape-pipes, with their openings directly under the chimney C, as seen more particularly in Fig. 3.

D is a saddle properly arranged on top of the boiler, upon which is supported an inner jacket E and an outer one F, sufciently separated to leave space for a tier ot' pipes G, whichV may be vertical, as shown in the drawings, or laid in coils through the space between the jackets. ets are united by a plate or ring a, and they are closed at the bottom by the flange l) ot' the saddle I), soI as to make a tight chamber between them, in which the hot-water pipes are arranged.

From each of the escape-pipes B B leadsa steam-pipe c c, which, passing up through the luespace H and through the flange b of the saddle, extends a short distance into the cham- Thetops of the two jackber inclosed between the jackets. Steam being thus introduced at the lower end of the chamber, it rises by its force, surrounding the pipes contained in said chamber and imparting its heat to said pipes and the supply-water contained in them. As the steam condenses, it falls toward the bottom of the chamber, and what steam remains passes ott through the pipes d CZ, which, entering through the ring a, pass down to near the bottom of the chamber, as seen in the drawings, and as low or a little lower therein than the top of the inlet-pipes c.

The pipes c d, as shown in Figs. l and 4, do not stand one over the other, as this would afford a direct passage for the entering steam to escape without spending its heat on the supply-pipes, the object being to cause it to circulate through, over, or around thel supplypipes beforeit escapes. Thetops of the escapepipes, after they pass through the ring a, are

curved orbent around, so that the passage ot' the steam therefrom shall not be direct, but somewhat checked in its transit through them. Cocks c c are also inserted in. the in'- let-pipes c c, from which rods may extend to the engineer, so that hemay control the passage of steam into the case or shut it off entirely,if required. This in nowise interferes With the passage of the products of combus- .tion or the necessary escape of the main portions of the steam through the chimney to promote draft therein.

The condensed steam or water in the case settles down between small vertical iianges on the top of the flange I) or into a groove or depression therein, and is carried off by a drip-pipef, Figs. l and 3, clear of the boiler, so as not to wet, corrode, or stain it.

Over the top ot' the chimney is a dome l, slightly raised above it, with a point g centrally placed on its under side, which divides and directs the escaping product, throwing it off to the periphery of said dome.

h, Fig. 1, is the inlet to the series of pipes G in the case, to which is connected the pipe leading from the feed-pump, and t' the exit, to which the pipe leading from the heater t0 the boilers is attached. These pipes may be furnished with check-valves similar to those represented in my patent of February 5, 1856, and need not be shown herein.

The red lines in Figs. l, 2, and 3 may represent-the outside Shell or ense that Covers the l (I, so :Li-ranged as to cause the steam to eil'n chimney, heater, &e., it being' of the common kind and supported on the saddle D.

Having thus fully described the nature and Object of my i1vention,\v1mt claim therein as new, and desire to secure by Lett-ers Patent, is-

In Combination with the ehmnber ineiosing; the heating-pipes, the inlet and exit pipes c eulzite over, around, or through the heating'- pipes 'before it escapes, as herein set forth and explained.

PETER S. EBBERT.
